EPECIPICATION forming part of Letters Patent No. 355,294, dated January 4, 1887.

Application filed April 2, 1886. Serial No. 197,581. (No model.)

To all whom it may concern:

I the rim, the rib O, and the outer edge of the Be it known that I, Hnnnr W. BELDS- pieces is extended to form the flange c, which MEIER, of the city of St. Louis, Missouri, have made a new and useful Improvement in Belt- Pulleys, of which the following is a full, clear, and exact description.

The improvement relates to belt pulleys whose construction is composite-that is, having the rim, spokes, and hub made separately IQ and united to form a pulley. In the present instance the rim and spokes are of wrought metal, and the hub is of cast metal.

The improvement, however, relates rather to the mode of constructing the pulley parts and 1 of uniting the hub and spokes.

In the annexed drawings, making part of this specification, Figure l is a side elevation of theimproved pulley. Fig. 2 is a crosssection on the line 2 2 of Fig. 1, and Fig. 3 is a section on the line 3 ot Fig. 1. The last two views are upon an enlarged scale.

The same letters of reference denote the same parts.

A represents the pulley-hub. It is perforated centrally ata, in the customary manner, is enlarged in the plane of the pulley to form a boss, at, and at the points where the spokes connect with the hub the boss is preferably extended to form projections a which enter 0 the spokes a short distance, and thus serve as an additional means for connecting the hub and spokes.

The spokes B are hollow, as is also the rib C. These parts B O are in practice formed together out of two similar pieces, D D, of sheet metal, which, by means of suitable dies or stamping-tools, are shaped to form, when turned toward each other and fastened together, the spokes and rib, substantially as 0 is shownthat is, beginning at that portion which connects immediately with the hub, the pieces D D are shaped at b to fit upon opposite sides, respectively, of the hub. The boss a, and, if desired, the extreme inner portion,

tion a of the hub.

To form the spokes, the pieces D D open apart from each other, in order to form the spokes hollow. At each side of the spokes Between the spokes the pieces D D are preferably cutaway at (Z. In the vicinity of the rim E the pieces D D open apart, to form, in conjunction with by means of the bolts F, which pass laterally through the" pieces D D and hub boss; and to more effectuallyunite the pieces D D with the hub the parts or washers G G, of some such material as cast-iron, are laid against the parts I), and the bolts F are passed through the washers, pieces D D, and hub-boss, the threaded endf of the bolts engaging in the farther washer, G, as shown in Fig. 3.

The present pulley, by reason of its spokes and rim-rib being made hollow, as described, is notably strong, stiff, and light.

The improvement is adapted to wheels as well as to pulleys. Then the washers G G are not used, the bolts, by means of nuts or other suitable means, can be made secure in the hub, and so as to fasten the pieces D D to the hub; and a further modification of the construction is casting the washers in one piece with the hub, and so as to cast the pieces D D into and thereby secure them to the hub, and thus dispense with the bolts F.

I claim 1. The combination ofthe hub A, having the extensions a a with the piecesD D, shaped, as described, to inclose the extensions a a and to form the hollow spokes and rib, and the pulley-rim, substantially as described.

2. The combination of the hub A, havingthe extensions a a the pieces D D, shaped, as de scribed, to fit said extensions and form the hollow spokes and rib, the washers G G, the bolts
